<span>Some of them remained in space, some ended up in the gas giants, Jupiter, Saturn, etc. A good percentage ended up in the sun</span>
Answer:
currently model of the atom shows an atom that is mostly empty space. In the center is a small nucleus made of protons and neutrons. The nucleus contains nearly all the mass of an atom. Surrounding the nucleus is a cloud-like region with electrons moving too fast and too unpredictably for us to know their location
Explanation:
<h3>Procedural steps are: - </h3>
- On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
- To start the reaction, sodium hydoxide (base) is added.
- To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
- TLC monitors the reaction's progress to ensure that no time is wasted.
- To remove any remaining water, the reaction solution is dried over calcium chloride.
- Column chromatography is used to purify the product, and evaporation is used to collect it.
<h3>What is Catalysis?</h3>
Catalysis is the process of boosting the pace of a chemical reaction by using a catalyst. Catalysts are not consumed in the reaction and so survive it.
